Very rare, first and only early edition of this most interesting alchemical treatise on spagyric medicine, complete with its second part, of particular interest in connection to the history of Brittany. Le Baillif was the personal physician to Henry I of Rohan in Brittany where he composed these two remarkable works. He was prosecuted by the Paris faculty of Medicine for his works, particularly the first work in this volume, the ‘Demosterion’, as they were not in conformity with the teachings of the Sorbonne. He was defended by Etienne Pasquier and finished by avoiding all condemnation. The faculty then published three works which called on the King to defend against charlatans. His works however were influential, particularly on the ‘Chimistes’ at the court of Henri IV.

In the first work Le Baillif ambitiously takes on the task of proposing a ‘sommaire véritable de la médecine paracelsique’. His dedication takes the form of a defence of Paraclesic medicine, not as a new form of medicine, but as medicine that rediscovers Hippocrates’ original intentions and methods. He gives a very methodical exposé of the fundamental principles of the doctrine, the four foundations of which are philosophy, astronomy, alchemy and virtue.He divides the work into five parts; three hundred aphorisms in French and Latin taken from Paraclesius, a brief discussion of magic, a dictionary of terms and finally a text on chiromancy.

The second work is of particular interest to the history of Brittany as in it Le Baillif gives the location of three ‘bains’ or sources containing minerals that, according to his theses, could cure a variety of illnesses. This was due to the particularly high mineral and metal content of these waters which Le Baillif claimed could cure such illnesses as paralysis or leprosy according to spagyric theory. He claims to have risked his life many times over in the search for these sources. The second source contained water that was so charged with ‘Taclh et amyanthe’ that when the sun shone it was difficult to keep yours eyes on it, so much it became mirror like. Its particularities make it a cure for contractions, and colic. He claims to have found traces of metals in the ‘Massif Armorican’ and that the waters from these hills would carry these metals and could cure illness because of their high metallic quality. He also made a study of the stones and fossils of the area including such things as ‘La dent Amorique’ or the ‘Crapudine’. These stones, it has been suggested, could have referred to fossilised teeth or even to neolithic arrowheads.
